SPECIFICATION forming part of Letters Patent N0. 695,342, dated March11, 1902.

Application filed November 1,1901. Serial No. 80,815. (No model.)

Be it known that I, I/VILLARD SALISBURY REED,'a citizen of the UnitedStates, residing at Smyrna, in the county of Kent and State of Delaware,have made certain new and useful Improvements in lVIanicure-Knives, ofwhich the following is a specification.

Myinvention is an improved manicure implement designed for use incutting, trimming, filing, scraping, cleaning, and otherwise caring forthe nails of the fingers and toes; and the invention consists in certainnovel constructions, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side view of my implement with the tileand ordinary blade open. Fig. 1 is a detail cross-section on about linea; m of Fig. 1. Fig. 2 is a crosssectional view on about lines 2 2 ofFigs. 1 and 3. Fig. 3 is a partial longitudinal section of theimplement. Fig. 4 is a detail perspective view of one end of the handle.Fig. 5 is a detail perspective view of the rotary cutter and its shaft.Fig. 6 is a detail perspective View of the liners. Fig. 7 is a detailperspective View of the screw for securing the cutter-bar. Fig. 8 is adetail perspective view of the cutter-bar. Fig. 9 is a detailperspective View of one of the antifriction-rollers. Fig. 10 is a detailperspective View of the locking-key. Fig. 11 is adetail elevation of thebutt-end of the implement on an enlarged scale.

The handle A is provided at one end with the blades B and O and isconstructed at its other end to support the rotary cutter and the partswhich cooperate therewith, as will be more fully described hereinafter.The blade B is an ordinary knife-blade and, like the blade 0, may besecured in the handle A.

and springactuated in the ordinary manner. The blade 0 is of a specialconstruction, having file-surfaces O on its opposite sides and providedat its outer extremity with a portion 0 which operates as a nail-cleanerand is separated by a slot 0 from a portion 0, which is formed as alifter for lifting up or pressing back the flesh and skin at the root ofthe nail, as is desired in the lnanicuring operation. The outer edge ofthe blade 0 at C is curved in a concave line and sharpened or brought toan edge to adapt it for use in B and 0 formed to support the rotarycutter which is used for trimming the nails. To this end I form suchhandle with a recess D in its extremity, from which extendslongitudinally inward a bore or opening E, which receives the shaft F ofthe cutter F. The recess D is open at its lower edge at D, and the boreE is intersected slightly in advance of its rear end by a channel G, inwhich is inserted the key II for the purpose of locking the cuttershaftF in place, as shown in Fig. 8. The outer surface of the handlesurrounding the cutter F is rounded from side to side, as shown at A inFig. 4, and slopes gradually upward toward its outer end, as shown at Ain Figs. 1 and 3, thus forming a guard for the cutter F and the abutmentfor the forefinger of the hand holding the knife in operating upon thenails. On its inner side the handle is provided with a projectingportion I, which lies between the lateral shoulders a on the handle Aand is spaced at its end 1' back from the outer end of the hub portion.I, providing a shoulder a. The inner end of the lug or projection I isadapted at t" to form a seat for the head 71 of the locking-key H, andthe threaded opening is provided at i for the screw K, which secures thecutter-bar to its place, as shown in Figs. 2 and 3. The cutter has itsshaft provided near its inner end with a groove f, which is entered bythe bifurcated end h of the locking-key H and is provided with theoutwardly-facing shoulder f adjacent to the groove f, which shoulder fforms in connection with the rotary cutter F an annular groove in whichis seated the antifriction-rollers L. (SeeFigs. 2 and 3.) In practicethe portions of the shaft lying on opposite sides of the groove f aremade smaller than the bore E in the end of the handle, so there will beno friction between the said shaft and the handle; but the shaft will beborne entirely by the antifriction-rollers, as will be understood fromFigs. 2 and The cutter-bar M is of a special construction, having thehollow or mortise M, which fits over the lug or projection I, and hasthe side flanges M which lap on opposite sides of said projection or lugI, and the end flange M which stands in operation in frontof the outerend of the said lug I. This cutter-bar has the opening M for the screwK, which opening is elongated longitudinally, so the cutter-bar can beadjusted in such direction to take up wear in the use of the device, aswill be presently described. At its rear end the cutter-bar overlies thekey H and locks the same in position, as shown in Fig. 3, and at theouter end of the said cutter-bar there is formed the neck N, whichsupports the point N, whose sides slope gradually, as shown in Fig. 8,and thus aid in guiding the nail into contact with the rotary cutter. Itwill also be noticed that the outer extremity of the cutter-bar at N issquare to prevent the implement from cutting into the quick, such end Nforming a stop to limit the movement of the rotary cutter toward theflesh. The neck N, as will be understood from Figs. 1 and 8, provides athroat which opens at the opposite sides of theimplement (seenin Fig. 3)and forms an outlet for the cut portion of the nail.

WVithin the recessed portion of the cutter-bar M and between thecutter-bar and the lug I, I arrange a suitable number of thin plates orliners O, which operate as washers to space the cutter bar away from thecutter and which can be removed from time to time as the parts wear totake up wear and insure the proper adjustment of the cutter-bar to thecutter at all times.

In adjusting the parts to position for use-it will be understood thatthe rotary cutter D has its shaft, with the rollers L applied, insertedin the bore E until the cutter F lies within the recess D, as shown inFig. 3, and projects at its inner edge beyond the side walls d of suchrecess, which slope rearwardly, as

shown in Figs. 3 and 4:. The groove f will then lie opposite the channelG, and the key II will then be inserted to the position shown in Fig. 3,in which it will fit within the groove f and operate to prevent anylengthwise movement of the cutter F and its shaft. Said cutter willthen be held within the handle and will be supported so itcan turnwithin the antifriction rollers, thus relieving friction and renderingthe rotation of the cutter very easy. The cutter-bar will then beapplied, as shown in Figs. 2 and 3, and held by the screw K with theliners O in place, which liners can be removed from time to time asdesired. When so applied, the cutter-bar will overlie the key H at itsinner end, and thus lock said key in place. At its outer end thecutter-bar will cooperate with the cutter F and will also operate as astop to prevent cutting into the quick of the finger or toe. It will benoticed the rotary cutter F is of concavo-convex form with the concaveface outward and the convex face on its inner side, such convex faceforming a shoulder opposite the shoulder f and retaining the rollers Lat the outer ends of said rollers. In operation the finger is applied asshown in Fig. 3 and the cutter will roll around from side to side andtrim the nail ofi close, and yet will be prevented from cutting into thequick. It will'be noticed from the foregoing that the cutter-baroperates below the nail and the rotary cutter above, with the cutter-barholding the nail to the knife and aiding in the cutting operation. Theconcave face of the knife or cutter F operates close to or against theface of 'the cutter-bar at a (see Figs. 1 and 3) and against the nailwhich is being trimmed, and it will be seen that the knife F fits itselfto the nail and will turn arou nd the smallest or roundest nail withoutpulling upon the nail or running off of same and will so travel untilthe knife has cut the entire nail across or around the end of the nail.The convex side of the knife turns against the portion of the nail whichis being cut off and turns such portion of the nail off downwardover'the cutter-bar or into the throat or opening at 01, allowing theknife to cut through the nail very easily and at the same timepermitting the knife to turn around the end of the smallest nail, asbefore stated. This knife F is self-sharpening, its shape being such asto cause its concave side, which runs against the face of the cutter-barand working and rubbing against such cutterbar with sufficient force towear the knife sharp as fast as the cutting of the nail dulls it. Byreason of the convex side of the knife as the knife is cutting throughthe nail the cut nail forces the concave side of the knife against theface of the cutter-bar and aids in keeping the knife sharp, as desired;

As best shown in Fig. 3, the handle is'provided with asolid wall atPbetween the'channel G and the bore E and the recesses Q for the blades13 and C, so no dirt or dust can get from the blade-recesses into theoperating portions at'the butt-end of the handle; I also show in Fig. 3the ends of the springs for actuating the blade 0; but as such springsmay be of the ordinary construction they need not be described in detailherein.
